From Digital to Physical

ProtoFab uses the very latest 3D printing technology in combination with a vast range of materials and alternative manufacturing solutions to bring to life even the most complex of prototype designs. With ProtoFab, the possibilit

ProtoFab's origins go back to 1996, when former chemistry teacher Jack Wu started offering rapid prototyping services for the nascent industrial design market in China.

The company he founded, Duch Group, is now one of the world's leading manufacturers of custom prototypes and on-demand production services. With three manufacturing facilities across China, Duch Group is able to offer design assistance, rapid prototyping, low-volume manufacturing, and mass production to clients all over the globe.

Duch Group launched the ProtoFab project in 2014, offering industrial-grade stereolithography 3D printers fine-tuned for cost efficiency and offered as part of unrivaled production services package.

Stereolithography, also known as SLA for short,is an additive manufacturing process, it is the veteran of 3D printing technologies. It is one of the most widely-used rapid prototyping technologies for plastic models.

Selective laser melting (SLM) is a particular rapid prototyping, 3D printing, or Additive Manufacturing (AM) technique designed to use a high power-density laser to melt and fuse metallic powders together.

Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power source to sinter powdered material (typically nylon/polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.

With two decades of offering on-demand production and prototyping services, ProtoFab is the perfect partner for bringing ideas to life. We have a wide range of processes and materials to choose from, each with its own benefits and applications.

Robusta G

Robusta G is an ultra-tough white plastic that is hard to break and can handle challenging builds. It acts as a replacement for CNC-machined polypropylene or ABS and is ideal for producing master models for vacuum casting.

Magna W120

The primary characteristic of Magna W120 is its strong resistance to heat (up to 90 degrees Celsius). It is also a highly robust material resistant to a wide range of substances, including solvents and oil.
